Experimental Assessment of Steel Fibre Reinforced Concrete Beam Strengthened with Carbon Fibre Reinforced Polymer
Due to an increase of load-carrying capacity, rigidity and stability of building structure become limited to accommodate the space. Thus, most of the structural elements experienced excessive cracking and this can endanger the structure. To overcome this problem, this paper presents the experimental assessment of steel fibre reinforced concrete (SFRC) beams strengthened with carbon fibre reinforced polymer (CFRP) using acoustic emission (AE) technique. An experimental investigation was conducted to obtain the crack propagation of the reinforced concrete (RC) beam under monotonic load. Three RC beams sized 150 × 200 × 1500 mm were tested. The first beam was designed as a control beam with no steel fibre added (B0SF0C), the second beam was added with 1% steel fibre based on concrete weight (B1SF0C), and the third beam was added with 1% steel fibre and strengthened with CFRP on the soffit (B1SF1C). The relationship between AE signal strength, load and time for all beams were analysed and observed the crack modes of the beams. It was found that the B1SF1C produced the highest signal strength when reached to the localization of shear crack due to the presence of CFRP that provides higher strength and stiffness. The experimental results indicate that the SFRC beam strengthened with CFRP was the highest in strength among other beams. Furthermore, the relationship between signal strength and crack modes of the beams is good. Hence, this study is significantly prime to enhance the performance and integrity of the structure.
